The prefrontal cortex (PFC) allows us to engage in what scientists call “cognitive control” (also known as “executive functioning”) and it is crucial for our sense of self. This video explains what the PFC is, why this brain region’s properties make it well suited to cognitive control and the sense of self, and how each of the subdivisions of the prefrontal cortex contributes to these functions. Includes interview clips with neuroscientists David Badre (Brown University), Gregory Hickok (UC Irvine), and Taylor Guthrie (University of Oregon).
